Title: Ferroelectric liquid crystal
Inventor: SATO MASAHIKO
IPC: G02F1/13
Filed: 1988-09-26
Abstract: PURPOSE:To decrease the influence of ionic impurities and to improve performance by using a ferroelectric liquid crystal having spontaneous polarization of a specific value or below. CONSTITUTION:The ferroelectric liquid crystal having the spontaneous polarization of <=15nC/cm<2> is used. An electric field in the liquid crystal layer by this polarization charge even in the state of not impressing an external electric field to the liquid crystal is, therefore, not formed and the unequal presence of the ionic impurities in the liquid crystal layer is obviated by the presence of the spontaneous polarization. As a result, the ionic impurities do not restrain the spontaneous polarization of the liquid crystal molecules on the contrary and, therefore, the ferroelectric liquid crystal which exhibits bistability in a normal state do not have monostability and the degradation in the contrast ratio is prevented. With respect to the response speed, a satisfactory solution is obtainable by a method for lowering the viscosity of the ferroelectric liquid crystal or for increasing the intensity of the external field or the like. The reliability of the ferroelectric liquid crystal element is improved while the dominance of the ferroelectric liquid crystal over a TN type liquid crystal is maintained.

Title: Optical receiving circuit
Inventor: TAKAHASHI YASUSHI
IPC: H04B10/67
Filed: 1998-08-28
Abstract: PROBLEM TO BE SOLVED: To reduce the power consumption of an optical receiving circuit by connecting the gate and drain electrodes of a P-channel FET having its source electrode connected to a power supply to a connection point set between a resistance connected to the power supply via one of its both ends and a light receiving diode and also connecting a capacity connected to a power supply or the ground via one of its both ends to the above connection point. SOLUTION: When a photodetector 1 receives the optical input, a photolelectric current proportional to an input level flows and is converted into voltage by a resistance 3. This voltage secures an averaged optical signal owing to the connection of a capacity 7. The FET 4 and 5 are turned on by the gate voltage change and the power Vcc is supplied to a preamplifier 2 and a next-stage amplifier 6. When the large optical input is supplied to the photodetector 1, the voltage drop of the resistance 3 is increased and it's impossible to secure the bias voltage enough to attain the normal operation of the photodetector 1. Thereby, the drain and gate electrodes of the FET 4 are connected together. When the gate voltage excessively decreases, a current flows to the photodetector 1 from the drain electrode to prevent the lowering of gate voltage.
